EPSS

EPSS est un modèle de notation qui prédit la probabilité qu'une vulnérabilité soit exploitée.

Score EPSS

Le modèle EPSS produit un score de probabilité compris entre 0 et 1 (0 et 100 %). Plus la note est élevée, plus la probabilité qu'une vulnérabilité soit exploitée est grande.

Percentile EPSS

Le percentile est utilisé pour classer les CVE en fonction de leur score EPSS. Par exemple, une CVE dans le 95e percentile selon son score EPSS est plus susceptible d'être exploitée que 95 % des autres CVE. Ainsi, le percentile sert à comparer le score EPSS d'une CVE par rapport à d'autres CVE.

These details were obtained through the Packet Storm Bug Bounty program and are being released to the community. +------------------------------------------------------------------------------+ +---------+ | DETAILS | +---------+ The heap memory buffer overflow vulnerability exists within the WebKit's JavaScriptCore JSArray::sort(...) method. This method accepts the user-defined JavaScript function and calls it from the native code to compare array items. If this compare function reduces array length, then the trailing array items will be written outside the "m_storage->m_vector[]" buffer, which leads to the heap memory corruption. The exploit for this vulnerability is a JavaScript code which shows how to use it for memory corruption of internal JS objects (Unit32Array and etc.) and subsequent arbitrary code execution (custom ARM/x64 payloads can be pasted into the JS code). +------------------------------------------------------------------------------+ +------------------+ | PROOF OF CONCEPT | +------------------+ The full exploit code is available here: http://packetstormsecurity.com/files/123088/ https://gitlab.com/exploit-database/exploitdb-bin-sploits/-/raw/main/bin-sploits/28081.tgz +------------------------------------------------------------------------------+ +---------------+ | RELATED LINKS | +---------------+ http://lists.apple.com/archives/security-announce/2012/Nov/msg00001.html http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2012-3748 +------------------------------------------------------------------------------+ +----------------+ | SHAMELESS PLUG | +----------------+ The Packet Storm Bug Bounty program gives researchers the ability to profit from their discoveries.
